VALVE.

SPECIFICATION forming part of Letters Patent No. 258,592, dated May 30,1882,

Application filed January 27, 1882. (N0 model.)

To all whom it may concern Be it known that I, JEREMIAH OMEARA, acitizen of the United States. residing at New York, in the county of NewYork and State of New York, have invented certain new and usefulImprovements in Valves; and I do hereby declare the following to be afull, clear, and exact description of, the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and

to letters or figures of reference marked thereon, which form a part ofthis specification.

This invention is in the nature of improvements on the means forsecuring the disk-holders to the valve-stem, and for locking the separable boxes shown anddescribed in my United States Letters Patent Nos.240,7 54 and 240,7 55, dated April 26, 1881; and the object oftheinvention is to simplify the construction without impairing, but, onthe contrary, increasing, the efficiency of the same.

To these ends the invention consists, first, in providingthe valve-seat,disk, or disk-holder, or its equivalent, in globe, gate, angle, check,and similar valves, gage-cocks, water-cocks, and all valves for steam,water, or gas fittings, with a grooved projection adapted to be looselyslipped on the end of a stem and held thereupon with freedom of motion,so as to become self-adjusting by means of an annular cap inclosing saidgrooved projection and locked down thereupon byasuitable pin; and,second, in providing a wrench on the thread of the bonnet below thedivided box, which wrench has a projecting handle, by which it may beoperated by a finger of the hand used to turn the valve in operating thesame for the purpose of holding the box against displacement by thesticking of the stem iherein,all as hereinafter set forth and claimed.

In the accompanying drawings, in the several figures of which similarletters of reference indicate like parts, Figure 1 is a side elevationof the bonnet, stem, disk-holder, and wrench containing my invention.Fig. 2 is a vertical section of the same with the stem in elevation.Fig. 3 is an elevation of the end of the stem. Fig. at illustrates thepin before and after its application. Fig. 5 is a bottom plan view ofthe annular cap. Fig. 6 shows the disk-holder in top plan view and sideelevation, and Fig. 7 is a top plan view of my wrench.

I have purposely omitted from my drawings a valve-shell, because I donot limit my invention to any particular kind of valves.

The stem or spindle aand the bonnet I) may be of any approved form.

a is a fixed collar on the valve-stem, and dis another collar below it.A hole, e, is made transversely through the collar 0.

fis a disk-holder similar to those shown in my patents above referredto, or it may be of any other construction, as desired,it being thedisk, plug, or sent usedfor opening and closing a valve. I provide aprojection, g, on top this holder, and form in it an undercut or L-shaped groove, which will afi'ord parallel lips it, by meansof which theprojection is adapted to be loosely slipped over the collar d of thestem, with the lips t t between the two collars on said stem.

It is an annular cap, adapted to fit closely but rcmova-bly upon thecollarc, and the flange l whereof is adapted to fit over the projectiong of the disk-holder when said disk-holder is in place on the stem. Bymeans of this cap the disk-holder is prevented from lateral displacementfroin the stem,but at the same time allowed free movement upon said stemto admit of its adjusting itself to any inequalities of its bearing, andalso allowed free rotation on said stem. The cap is held in place uponthe projection of the disk-holder by means of a pin, m, passed throughthe hole a in the collar o and held therein by having its ends bentback, substantially as shown. By this construction the disk-holder isreadily attached to and detached from its stem, and by a very simple andcheap means. \Vhen to be disconnected the pin is removed and the caplifted off the projection, when the said projection can be easilyslipped, in fact will fall, off the stem.

Difficulty has been experienced in getting at thebox-locking nut in thevalves heretofore used, and the employment ot'independent tools tooperate it has been necessary; this, too, at an inconvenience, loss oftime, and expense. I obviate these objections by providing on the threadof the bonnet 1), below the box a, a movable screw-th readed wrench, 0,having projecting handles 1). As the operator turns the handwheel of thevalve, if the box is moved with it by the sticking of the stem and box,the operator can reach down with a finger of the hand, or with the otherhand turn the handled wrench up against the box, and thus stop itsbacking or running off.

Valves provided with my box or gland locking device can be used inparlor-radiators with great assurance of freedom from damage by leakage,as this wrench is adapted to be operated by even the most nnskillfulwhen a leak is discovered.

I do not limit the application of my invention in this wrench tovalve-glands, since it is quite obvious that the wrench is equallyapplicable to stuffing-boxes generally.

What I claim is- 1. A valve-seat, disk, disk-holder, or plug adapted tobe loosely connected to a stem or spindle, combined with a loosesuperposed cap and independent means to hold said cap in place,substantially as described.

2. A valve-stem having a collar on its end, a disk, or its describedequivalent, having an undercut grooved projection to fit over suchcollar, a cap on said stem provided with a flange to embrace suchprojection to prevent its lateral displacement, and a pin secured in 0the stem abovethe cap to hold said cap against vertical displacementanddown upon the projection of the disk, substantially as shown andspecified.

3. A valve-stem provided with a collar on its end, a disk, oritsdescribed equivalents, provided with parallel lips to embrace suchcollar, an annular cap on the stem having a flange to inclose said lipsand collar, and means to prevent the vertical displacement of such cap,substantially as shown and specified.

4. A threaded wrench provided with a handle and applied to the threadedbonnet of a valve below the box or gland thereon to hold such box orgland against being backed or run off by the turning of the valve-stem,substantially as shown and described.

5. The combination, with athreaded bonnet and a box thereupon, of ahandled wrench applied below such box on the bonnet, substantially asand for the purpose described.

6. The handled Wrench 0, combined with an independently-movablestufling-box or gland to hold such box or gland against accidentaldisplacement, substantially as specified.

In testimony whereot'I aflix my signature in presence of two witnesses.

JEREMIAH OMEARA.
